OpenBazaar-Server crashes after submitting form to "Complete Order"

[zmingee]

Brief Description: When completing an order/contract, after filling out the review and such, when I click "Save", the server immediately crashes. Upon restarting the server, the contract is still waiting to be completed.

Reproducible (Always / Almost Always / Sometimes / Rarely / Couldn't Reproduce): Always

Steps to reproduce:

1. Have a contract ready to "complete"
2. Click "Complete Order"
3. Fill in "Review section" and select stars
4. Click "Save"
5. Server crashes.

Observed Behavior: Instant crash on server side.

Expected Behavior: This is my first contract to complete, but I would imagine that it's supposed to go to the next "completed" stage.

Also, for what it's worth. I just completed an order on the local desktop app (bought a sticker from OB1) and it worked fine. Application did not crash. I'm guessing this is limited to the server.

howdy there, i'm the seller here. I had to restore a backup a while ago and I have made sales since then without a hitch. Every error I get seems to be a version of http://pastebin.com/uVUA9bxf

[SamPatt]

@zmingee We're taking a look now, sorry for late response.

[zmingee]

@SamPatt I just wanted to follow up on this bug report. It's been over a month now and the seller still hasn't gotten paid.

I've tried everything I can think of: I've updated and reinstalled all the dependencies on my side, updated OpenBazaar-Server (from master branch), resized the VM from 1c1g to 2c4g just in case it was memory related, etc., and I still get the same error. At this point I'm not sure if it's on my end or the seller's end.

[ghost]

@zmingee I'm very sure the problem is on my end. I took some notes about the source code and what could have gone wrong, but I'm not at home

EDIT: I didn't know he had a segfault on his end. It might be both?

Will have to return to this this week.

Thanks, no rush, and merry christmas
